🧪⚛️ A collection of all of my posts about basic concepts in condensed matter and nanoscale physics, updated for the first time in 6.5 yrs. Hope this is useful, and please let me know what else you'd like to see. nanoscale.blogspot.com/2026/01/upda...
A majority of my senior Intro to Solid State physics students use LLMs to answer their basic questions & solve their homework, which is a huge bummer. (My least-attended office hours ever.) But an even bigger bummer is that it doesn't even give correct answers to simple questions. Barf.
You know this #Dodgers game is going long (~7 hrs now) when the announcers are talking about how good the "glistening" fruit tray looks 😂
#WorldSeries
Bonus: They made us dead last to board so we can’t even ASK if someone wants to switch seats because it’d be way too burdensome. Terrible customer service with no compassion/empathy.
Worst flight experience flying American Airlines @americanair.bsky.social. Delayed 6 hrs. Told us our seats would be assigned “at the gate” which NO ONE WAS AT until 10min b4 boarding. Now my wife & I, traveling w our dog, can’t sit together. No apology, no explanation. Never flying them again.
I don't get it. I'm a university professor and am around young people all the time. In my lectures, I regularly call on students and ask them questions. I have never experienced this supposed "Gen Z stare" thing.
Gotta celebrate the few good things going on right now. Like our good friend & filmmaker Dehanza Rogers earning tenure at Emory. Celebrated at a Dodger game & got ourselves on the Jumbotron! #AcademicSky
If you had a mentee or know a student with a rescinded PhD offer or who is reconsidering attending a US school, this is an interesting opportunity from Queen’s University in Ontario, Canada. 🧪

🚨 Action alert: Two days left!!
Help protect NSF/NIH from political interference.
👎 A new rule (Sched. F) would allow for replacing career program officers with political appointees.
➡️ Action: Object here by THIS FRIDAY. Comments can be brief and/or anonymous. Helps future litigation.
Ha so true. It must be the default Nanonis color?
Atomically resolved image of bismuth strontium calcium copper oxide false-colored to appear as milk chocolate.
Bismuth strontium calcium copper oxide, BSCCO, or “bisko,” either way it sounds and looks delicious! Measured recently in our scanning tunneling microscope at #UCLA.
Absolutely STUNNED that Lorna Simpson says my work partly inspired a work of art 😮
“It was a reproduction of a collage from a series called “Sky Pinups,” partially inspired by Zora’s gift of a book called “The Disordered Cosmos,” by the physicist and Black feminist writer Chanda Prescod-Weinstein.”
Solid state physics is pretttttty. This is an image of the momentum-distribution of electrons inside of a crystal measured using the photoelectric effect.
From a recent trip to @als-lbnl.bsky.social.

Bill is the absolute best. I was part of an outreach event w/ him when I was a postdoc at #NIST years ago and I was just in awe of his level of enthusiasm & warmth for the kids visiting us that day. Amazing scientist & person.
Congrats!!!
Well that's helpful! I hope they stick to their timeline. Our STM was delivered over ONE YEAR late (27 months total). Wishing you better luck!!
5. And on the collaborator side, Jay Green of the Ni Ni crystal growth group at UCLA will show magneto-transport & ARPES measurements of a very interesting triangular anti-ferromagnet system containing (heavy!) Europium.

4. On Thursday, Kuan-Yu will show our Current-Tuned STM experiments that use an external in-plane driving current to tune the CDW phase coherence in a protoypical quasi-1D Peierls system: Either enhancing CDW phase coherence or lowering it through phase dislocations.
summit.aps.org/events/MAR-T...
3. On Tuesday, I will give a talk demonstrating the capabilities of our open-source software PyAtoms for quickly simulating scanning probe images of 2D materials, charge density waves, & moire systems. I'll also discuss how I use it in my Solid State courses.
summit.aps.org/events/MAR-F...
2. On Monday Morgaine will show STM results on applying HUGE amount of strain (~13%) to charge density wave material NbSe2. It's so large we convert from 2H to 1T & using atomic-resolved spectroscopic imaging STM we can visualize the gap closing & phase reversal.
summit.aps.org/events/MAR-A...
1. This week my group & I will be at #APSGlobalSummit2025 #APSMarch showing some of our exciting work discovering ways to tune correlated phases in quantum materials using external knobs like LARGE uniaxial strain or flowing current through them while visualizing these effects at the atomic scale.
The key difference is the boundary condition: By physical intuition of how an ideal fluid would flow past a boundary, the normal component of the velocity around the sphere should vanish (cf. conducting sphere where its the potential that vanishes). 🧪 #AcademicSky
Laplace's equation to solve for incompressible fluid flow around a sphere for my Math Methods class. This exact problem was on my PhD qualifying exam. I had never done a fluid mechanics problem in my life! What saved my ass was the analogy to a conducting sphere in a constant E-field. 🧪 #AcademicSky
This is a mega-thread of all Microsoft problems related to topological qubits.
NOTE: I skip the numerous news reports and press releases, this thread is for serious _scientific_ and procedural materials

My lab has high-voltage vacuum pumps & other electrical equipment that runs 24/7 all year long.
UCLA has its own fully-staffed **POWER PLANT** to supply the considerable power required for all of its medical and science research labs. F&A in part goes to running & staffing it.
Interested in an exciting PhD project working in a stimulating environment in the Centre for Designer Quantum Materials, combining cutting-edge experiments, bespoke instrumentation, complex data analysis and numerical modelling?

Grant decisions by something that cannot give the correct number of Rs in “strawberry” or even generate images of hands with the correct number of fingers 🙄
Ditto. Decades of effort, across administrations on both sides, to address the disparity in representation in the sciences.
My former student (and big Harry Styles fan) included a fun, harmless prank for beta-testers of PyAtoms: After prolonged use, a pop-up asked if you'd like to listen to his music on Spotify.
Now that PyAtoms is out of beta, this feature is discontinued. Farewell, Harry!
